Have you noticed any difference in performance the LSD of the 3.31 and the torsen in the 3.73?

You guys who are FI and have switched from 3.73's to 3.31's. Did you just switch out the gears or entire pumpkins? I just picked up a new 3.31 take-off pumpkin to replace the 3.73's, and now second guessing myself. I'll be doing occasional drag strip runs, so should I have just put 3.31 gears in my existing differential, so that I still have use of the torsen diff, or will the LSD be fine in the 3.31 pumpkin?

I switched out the gears so I could keep the Torsen.

I swapped the whole thing. Found a take off unit for 299$
I didn’t want to shatter my high dollar Torsen.

Thanks, I'm just going to swap pumpkins and hold on to the 3.73. I picked a take off up for under $300 as well.
